These Are the 11 Best Hair Diffusers for Defined and Bouncy Curls, According to Experts

There is no one size fits all approach to caring for curly hair. Anyone who is used to experimenting with styling their natural hair texture will know that curls come in so many different patterns and porosities, which means that products that work on my texture might not necessarily work for yours. However, when it comes to drying curly hair, experts agree that there is one tool that is non-negotiable when it comes to perfecting a curly blow dry and that’s a diffuser.

“Diffusers allow heat and very gentle airflow to ambiently dry curls without moving them around too much,” says expert hairstylist and hair trend forecaster Tom Smith. “It basically mimics the natural air drying process but sped up, and the curved bowl shape allows you to contract the curls while drying to further enhance their tightness and definition.”

Simply put, if you’re not already using a diffuser and you have curly hair then it might just be the secret to achieving more defined curls, shinier texture, and bouncier volume. But before we delve into our list of the best hair diffusers in more detail, I wanted to pick Smith’s brains on how to get the most of your diffuser if you’re new to using one.

Once you’ve attached your diffuser to your hairdryer, Smith points out that the key to success is using it on the lowest speed setting possible with medium heat. “Without touching the hair, slowly move the diffuser around your head allowing your curls to slowly dry and set,” explains Smith. Slow and steady is key here. “Don’t rush this process as excess touching will cause frizz,” he advises.

For extra curl definition, Smith suggests tipping your head forward. “Try using gravity by leaning your head over and letting your curls fall into the bowl of the diffuser, keeping it still in place for a few seconds before tipping a different direction to tighten, contract and enhance your curls.”

How do you prep hair before using a diffuser?

As someone that avoided using a diffuser for years because I never liked how my hair looked after using one, it turns out that I was missing one key step—prep. “You need to prep your curls with a suitable product and shake and scrunch your hair into the desired position before diffusing,” says Smith. “Olaplex No.10 is my top favourite curl product of the moment, thanks to its reparative and nourishing benefits without crispness or stickiness.”

And, most importantly, whether you’re prepping, diffusing, or air-drying your hair, Smith’s most crucial piece of advice for achieving curly hair is to try not to touch it. “The more you touch and move the hair while diffuse drying the more you’ll cause fluff, frizz and irregularities. Keep the hair still while drying and the curls will be more resilient and defined,” he explains.
